Bugged Fire Texture refers to a somewhat well known bug in Super Mario 64, where the fire texture will appear as corrupted. This is the result of a line of code to display the smoke texture calling for the "RGBA" format, even though the smoke texture is in the "IA" format. As a result, the games attempts to display an image in IA format in RGBA format, which results in the corrupted appearance of the image.
Discovery[]
The fire texture displaying correctly.
During the July 25th 2020 Gigaleak, it was discovered that the reason the fire texture looked so corrupted is due to the line of code mentioned above. After it was discovered, sites like Romhacking.net created patches for this glitch, that would make this line of code call for the correct format of the smoke texture. Due to this patch, the smoke texture would display correctly, as shown in the image.
Unfixed fire texture for comparison.
Phenomena[]
In certain personalized copies of Super Mario 64, this bug will be fixed. (Usually as a result of the The Self-Patching Anomaly.) However, in rare cases the Personalisation A.I. will corrupt the texture even more through various means.
